Timing Pulley Stock - Machining Question

[AdamHeard]

You can also make a psuedo-collet of sorts to us as an adapter with a 3-jaw.

Get a chunk of aluminum and bore it out to where the Id is just barely larger than the pulley, and size the OD such that the walls are pretty thin.

Clamp this collet in the 3-jaw with the pulleystock inside, and it should work.

We do this on the fly probably 5 times per season for various parts.
